Covering 6,641 square kilometers (2,564 square miles), Banff National Park lies on the eastern slope of the Rocky Mountains in Alberta, Canada. Banff was the first national park declared in Canada, and the third national park in the world. The park's origin lies in an accidental discovery of a cave containing hot springs in 1883. The park began as a 26-square-kilometer hot springs preserve. The Enhanced Thematic Mapper Plus (ETM+) instrument on NASA's Landsat satellite captured this true-color i...

The pressure and heat caused by this collision led to the formation of underwater volcanoes, some of which grew tall enough to...

|Las Cruces, New Mexico: Image of the Day - NASA -- Astronaut photograph eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS011&roll=E&frame=8410 ISS011-E-8410 was acquired June 9, 2005, with a Kodak 760C digital camera with an 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The http://spaceflight.nasa.gov/home/index.html International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC http://eol.jsc.nasa.gov/ Gateway to Astronaut Photography of Earth.|
The city of Las Cruces is located within the Rio Grande Rift, a large geological feature that extends from Colorado southwards into Mexico. The Rio Grande Rift is marked by a series of depressions (known as graben) punctuated with uplifted mountains. The grabens form when blocks of the Earth's crust sink as geologic forces pull the crust apart along fault lines. Sinking in one place is often accompanied by uplift along boundaries of the grabens -- the striking Organ Mountains to the east of Las ...

|San Andreas Fault from Shuttle Radar Topography Mission : Image of the Day - NASA -- Image courtesy NASA/JPL/NIMA|
The prominent linear feature straight down the center of this perspective view is the San Andreas Fault in an image created with data from NASA's Shuttle Radar Topography Mission (SRTM), which will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, California, about 100 kilometers (about 60 miles) northwest of Los Angeles...

|Floodwaters in Burma: Image of the Day - NASA -- NASA Image Of The Day|
In early May 2008, earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14810 Cyclone Nargis caused widespread flooding in Burma (Myanmar). Besides trying to assist the storm survivors, the international community also tried to determine the extent of flooding, but making such a determination can be difficult. Clouds often obscure satellite observations, and muddy-brown floodwaters typically blend in with the surrounding landscape, especially fallow cropland...

|Airborne Dust and Ash over Southern California : Image of the Day - NASA -- Image courtesy NASA/GSFC/LaRC/JPL, www-misr.jpl.nasa.gov/ MISR Team. Text by Clare Averill, Raytheon/JPL).|
The Santa Ana winds that typically blow through Southern California during late fall and winter swept large amounts of dust and ash across the skies of San Diego and over the Pacific Ocean on November 27, 2003. The intense brush fires that had swept through the foothills of this region in October left soils exposed and vulnerable to such strong winds. In this image pair from the Multi-angle Imaging SpectroRadiometer (MISR), a false-color nadir image (left) highlights the burnt areas, while a 3-...

|Giant Iceberg Drifts out to Sea: Image of the Day - NASA -- Image courtesy Jacques Descloitres, rapidfire.sci.gsfc.nasa.gov/ MODIS Land Rapid Response Team at NASA GSFC|
Over the past two and a half years, several unusually large icebergs have calved off of the Ross Ice Shelf in Antarctica. While some have made their way out into the Pacific Ocean to melt, others continue to shift and float slowly through the Ross Sea. Three of these icebergs can be seen in the above image, taken on November 17, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra satellite...
